ORVILLE M. MORSE, OF JACKSON, MICHIGAN, ASSIGNOR TO THE KNICKER- BOCKER COMPANY, OF SAME PLACE.

DUST-COLLECTOR.

SPECIFICATION forming part of Letters Patent No. 404,216, dated May 28, 1889.

Application tiled August 2G, 1886. Serial No. 211,899. (No model.)

To all whom, it may concern,.-

Be it known that I, ORvILLE M. MORSE, of the city of Jackson, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Dust-Collectors,

K of which the following is a specification.

This invention relates to an improvement in that class of dust-collectors in which the dust-laden air is caused to assume a rotative or whirling motion, whereby the dust is driven to the circumference of the whirling body of air and discharged, while the purified air, forming the inner portion of the whirling body, escapes in another direction.

The principal object of this invention is to provide simple means for intercepting and collecting` any minute particles of dust which may escape from the machine with the puriiied air.

My inventionalso has the object to improve the construction of the separatingchamber of the machine; and my invention consists to these ends of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure lis a sectional elevationk of my improved dustcollector. Fig. 2 is a horizontal section in line n; az, Fig. l. Fig. 3 is partly a top plan view of the machine and partly a horizontal section in line y fy, Fig. l. Fig. et is a vertical section through the dust-discharge Opeliing. Fig. 5 is a vertical section showing the dust-collector mounted on a dust-room.

Like letters of reference refer to like parts in the several figures.

A represents the separating-chamber of the dust-collector, in which the dust-laden air is caused to assume a rotative or whirling motion,whereby the dust particles are driven to the circumference of the whirling body of air. The chamber A is provided with a tangential inlet-spout, a, through which the dust-laden air enters the chamber in the proper direction to cause the air to assume a rotative movement. The peripheral wall ct of the separating-chamber is made inclined or tapering, whereby the dust is caused to tiow toward the small end of the chamber.

B represents the head which closes the large end of the chamber A, and which is provided with a central opening in which is secured a tubular imperforate guard or collar, l), which depends into the chamber A. The collar ZJ forms the outlet through which the purified air escapes from the chamber A.

.C represents the head which closes the small end of the separating-chamber, and which is provided at its circumference with an opening, c, through which the dust is discharged irom the chamber. The opening c may be short, as shown in Fig. 2,01' it may be extended to a greater or less length around the head C, as may be preferred. Vhen the dust-collector is arranged upon a close dust room, D, as represented in Fig. 5, the head C, resting on the dust-room, is provided with a central opening, d, through' which the air which enters the dust-room with the dust, through the openings c, is returned into the separating-chamber A. p y

E represents an inwardly-proj ectin g imperforate lip or iiange secured in an upright position to the inner side of the wall a of the separating-chamber A, at or near the inner edge of the inlet-spout a.. The lip or flange serves to break the air-current after the latter has made the circuit of the separatingchamber, thereby preventing the dust-collector from reacting or causing a back-pressure upon the fan by which the dust-laden air is set in motion.

F represents the supplementary dust-chamber surmounting the head B and receiving the outer annular layer of air, which is discharged through the tube l), while the inner body or bulk of the escaping air is discharged without entering the supplementary dustchamber. For this purpose the latter is provided with a central air-discharge tube, f, which is secured to the upper head, G, of the chamber F. The tube f depends in the chamber F and terminates slightly within the outlet-tube Z) of the separating-chamber A. The tube f is madel somewhat smaller in diameter than the tube b, so that it receivesonly the inner portion ofthe current of air which issues through the tube h, while the outer annular portion of this current passes along the outer surface of the tube f into the chamber IOO F. The air escapes from the separating chamber A through the tube I) with a rotative or whirling motion. Any dust parti cles which may be carried oli by this current of air are consequently found in the outer or circumferential portion of the outgoing air-eurrent and pass into the chamber F, while the inner portion of the air-current passes into the tube f and escapes at the upper end of the latter. The circumferential portion of the air-current, entering the chamber F through the space between the tubes l) and f, spreads in this chamber and is weakened, whereby the dust particles are permitted to settle. The. spreading of the air-currentin the chamber F is facilitated by a horizontal dei-lector, ll, which consists of an annular plate secured to the tube f in the chamber F, and leaving a space, 71, between its outer edge and the side walls of the chamber, through which the air passes upwardly. represents air-escape openings formed in the top plate, G, of the chamber F ,near the tubef. The aircurrent entering the chamber F passes outwardly underneath the defleetor lil and inwardly above the latter until it finally escapes through the openings 1'.. Inits course through the chamber F the air parts with any dust particles which it may contain and deposits the same either upon the head B or the dellector ll. The side walls of the chamber F are formed by removable panels or doors 7u, which are attached to cerner-posts Z, so that upon removing these panels or openin g these doors the accumulated dust can he removed.

I do not wish to claim in this application the construction of the separating-chamberper se, as that is claimed in another application tiled by me March 3l, JRSG, Serial No. 197,307.

I claim as 1nyin\'entionl. The combination, with the main separatingchamber provided with means whereby the dust-laden air is caused to assume a whirlingl motion, and which has an outlet for the purified air and a dust-discharge, of a supplementary dust-chamber provided with an air-passage of smaller size than the outlet of the separating-chamber, whereby the outer layer of the outgoing air-eurrent is turned into the supplementary dust-chamber, while the inner portion of the outgoing air-current is permitted to escape, and with an outlet through which the purified air escapes from the supplementary dust-chamber, substantially as set forth.

2. The combination, with a separatingchamber, A, having a head, B, and in the same an air-outlet, I), ot a supplementary du st-ehamber, F, having a tubular air-passage, a defiector, Il, arranged in a chamber, F, around the passage f, and air-escape openings i, substantially as set forth.

The combination, with a tapering separating-chamber, A, of a head, l, closing the large end of said chamber and provided with a central air-out-let, I), and a head, (l, closing the small end of "said chamber and provided with a peripheral du sil-discharge, c, and a eentral air-inlet opening, d, substantially as set forth.

fitness my hand this 21st day ol August, 1886.
